HUGH GRAHAM, OF DARTMOUTH, NOVA SCOTIA, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 317,120, dated May 5,1885 Application filed September 1, 1884. (No model.)

drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts inboth the. figures.

Figure 1 is an end view of a car provided with my improved car-coupling,the pin-being raised. Fig. 2 is a longitudinal sectional elevation ofthe end parts of two cars proyided with my improved coupling, one pinbeing raised and the other lowered.

The draw-head A, held on the under side of the car 13 in the usualmanner, has the usual apertures.

The coupling-pin D has its lower end beveled or curved downward andtoward the rear, and a short distance above the said lower end the pinis provided in its front with an offset or shoulder, E, which is solocated that when it rests on the draw-head the lower end of the pinwill be a short distance above the bottom of the draw-head, as shown.

From the pin D a rod, F, projects upward, the rod having its upper partsquared or flattened, which upper part passes through a correspondingaperture in a guide-arm, G, projecting from the end of the car near thetop. The rod is thus prevented from turning, andthe shoulder E willalways be at the front of the draw-head.

The rod F extends to the top of the drawhead, thus permitting of raisingthe coupling- 4 pin from the roof of the car.

Atransverse shaft, H, journaled on'the end of the car, is provided ateach end with a handle, J, and has a middle arm, K, connected by achain, L, with the top of the coupling-pin D.

The pin D is provided with a head, D, to prevent it from dropping toofar. i

The operation is as follows: To set the U coupling, the pin D is raisedand its shoulder E rested on the draw-head in front of the pin aperture.When the entering link N strikes the lower beveled end of the pin, itforces it upward sufficiently to pass under it, and also 1 pushes itinward, When the end of the link has passed the pin, the latter dropsand passes through the link, thus coupling the cars.

To uncouple, the pin D is raised from the,

top of the car by means of the rod F, or from the sides of the car bymeans of the shaft H.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a car-coupling, the combination,with

the draw-head A, of the coupling-pin D,'hav-.

ing a shoulder or offset, E, of the rod F, projecting upward from thepin and having its upper part squared, and of the guide-arm G,

- substantially as herein shown and described.

2. In a car-coupling, the combination,with the draw-head A, of thecoupling-pin D, the rod F, the arm G, the shaft H, the arm K, and thechain L, substantially as herein shown and described.
